Yes, you’re probably reading this on a Windows-based PC,

Nope.

What has happened, however, is that the desktop has become less important. The tablet may not have killed off the PC, but it certainly has given it a fever, and smartphones have it throwing up.

And these run on IOS and Linux.

I also need a real computer to get things done. A teeny tablet won't cut it,although the Ubuntu one looks interesting and it runs all my Linux apps!
